At DefCon last year there was seminar on plane hacking given by what I consider a definite expert. He was a commercial airline pilot and certified mechanic and a computer hacker to boot.
Other than the 777, the avionics of a plane do not use TCP/IP and therefore cannot communicate with a PC without a special adapter plugged directly into the avionics.
Awesome seminar, but the speaker did bring up the potential in the future if airplane builders were not careful.

The best Spot the Fed story I have heard was several years ago when DEFCON was at the Riviera.
The woman gets up and picks out the Fed. When asked how she knew, she became sheepishly quiet. After some prodding she admitted sleeping with him and while he was still asleep she went through his wallet and found his ID.

I took my niece to a One Direction concert, Arizona Cardinals Stadium, sold out.
If we ever wanted to make an Islamic terrorist talk, use a One Direction concert as torture.
A bunch of teenagers dressed provocatively trying to marry a band member.
It would drive them nuts, as it did me.

Wouldn't be awesome if you could activate an ink dye that exploded all over the person who stole your phone?
Recovering a stolen phone is pretty much hopeless, but at least you would have the satisfaction that the perp looked like a smurf.
Of course the downside, hackers would think it would be funny as hell to set off the dye on people they didn't like.

The problem with AZ is that the power company was paying 4 times the going rate to buy power from solar panel users.
In essence making the rest of the consumers pay for people's solar panels.
If it were the going rate, I would have no issue with solar panels, but why should I pay more so someone else can have solar panels?

It all boils down to companies paying tax to someone one, be it the government or airports in this case.
As long as everyone pays the taxes, no issues. Try to bypass the taxes and lawyers shall descend upon thee.

SFO is cheap compared to other airports for taxes, in Vegas it works out to be about 50% tax on top of the rental bill.
